Objective:To observe the efficacy of cytokine-induced killer (CIK) cells on patients with advanced lung cancer. Methods:A total of 90 patients with advanced lung cancer were identified from January 2011 to December 2013. CIK therapy was given to 41 pa-tients in the observation group, whereas the other 49 patients in the control group received the best support treatments without che-motherapy or radiotherapy within one month of inclusion. Following up was conducted for the patients in the two groups, and KPS scores, median survival, and adverse reactions compared. Results:The KPS score in the observation group was higher than that of the control group after treatment (P=0.034). The median survival period of the observation group was eight months, which was one month longer than that of the control group (P=0.044). Major adverse reactions included fever, joint pain, and insomnia, which were recorded 51.22%, 36.58%, and 29.27%of occurrence, respectively. Conclusion:CIK cell therapy improved the quality of life and pro-longed the survival of advanced lung cancer patients with tolerable adverse reactions.

OBJECTIVETo evaluate the effect of subgingival scaling/root planning (SRP) and occlusal adjustment on clinical and occlusal parameters in teeth with chronic periodontitis and secondary occlusal trauma.
METHODSEighteen patients with chronic periodontitis and occlusal trauma were included and randomly divided into group A and group B. On day 0, group A was treated by full-mouth subgingival scaling and root planning, and group B was treated by occlusal adjustment in occlusal trauma site. On day 28, group A was treated by occlusal adjustment in occlusal trauma site, and group B was treated by full-mouth subgingival scaling and root planning. Probing depth (PD), attachment loss (AL), bleeding index (BI) were evaluated on 0, 28 and 56 d, and the occlusal time (OT) and the percentage of occlusal force were evaluated on 0, 28 and 56 d in occlusal trauma site. The data was statistically analyzed.
RESULTSIn baseline, the PD[(4.42 ± 1.41) mm vs (4.36 ± 1.38) mm], AL [(2.75 ± 1.32) mm vs (2.63 ± 1.37) mm] and BI [(2.20 ± 0.81) vs (2.24 ± 0.89)] of the full-mouth showed no significant difference between the two groups (P > 0.05). There was no significant difference in PD [(5.21 ± 1.21) mm vs (5.08 ± 1.12) mm], AL [(4.94 ± 1.47) mm vs (4.89 ± 1.32) mm], BI [(2.61 ± 0.92) vs 2.50 ± 0.79)], OT [(1.29 ± 0.39) s vs (1.34 ± 0.35) s] and the percentage of occlusal force [(6.8 ± 2.1)% vs (7.4 ± 1.7)%] in occlusal trauma site between the two groups(P > 0.05). After SRP therapy, the PD,AL,BI and OT were significantly decreased (P < 0.05).The clinical parameters exhibited no significant difference after only occlusal adjustment(P > 0.05).On 56 d, the reduction in clinical parameters was not significantly different between the two groups(P > 0.05),however the reduction of OT and the change of the percentage of occlusal force in group A [(0.85 ± 0.41) s, (2.2 ± 2.2)%] were more significant than those in group B [(0.70 ± 0.38) s; (1.5 ± 1.6)%] (P < 0.05). After occlusal adjustment, the increase of OT in group A [(0.21 ± 0.11) s] was lower than that in group B [(0.67 ± 0.37) s]through the 28-day observation period (P < 0.05).
CONCLUSIONSOcclusal adjustment alone is inadequate for control and management of periodontitis.SRP therapy can eliminate the inflammation and decrease the OT of tooth with occlusal trauma.The combination of SRP and occlusal adjustment may achieve more stable results.

OBJECTIVETo evaluate the effect of low salt (LS) on the expression of cyclooxygenase-2 (COX-2) and the activity of nuclear factor kappa B (NF-kappaB) and activator protein-1 (AP-1) in the mouse macula densa derived (MMDD1) cell line.
METHODSMMDD1 cells were transfected with luciferase reporter plasmid containing AP-1 or NF-kappaB. Luciferase reporter assay was used to evaluate the effect of normal salt (NS) and low salt (LS) on the activities of NF-kappaB and AP-1. The changes of COX-2 expression were examined by RT-PCR. The expression of p-p38 MAPK, p-p44/42, c-Jun, c-Fos, and COX-2 in MMDD1 cells were analyzed by Western blot.
RESULTSThe expressions of COX-2 mRNA and protein in MMDD1 cells were significantly increased by LS (P < 0.01). Phosphorylated p38 and p44/42 MAP kinase were significantly increased by treatment at 180 min (P < 0.01). The up-regulated COX-2 protein expression with LS were significantly reduced with SB 203580 (p38 inhibitors) and PD-98059 (p44/42 inhibitors) (P < 0.01). The expressions of c-Jun and c-Fos were increased by LS. The luciferase activities of AP-1 and NF-kappaB were stimulated in LS (P < 0.01), the up-regulated luciferase activities were attenuated by PDTC at 25 micromol/L (NF-kappaB inhibitor) and curcumin at 20 micromol/L (AP-1 inhibitor) (P < 0.01). LS altered COX-2 mRNA abundance and protein expression were decreased in treatment with PDTC at 25 micromol/L, curcumin at 20 micromol/L (P < 0.01).
CONCLUSIONLS can induce the expression of COX-2 in MMDD1 cells, which may be involved in the activation of p38 MAP kinase, p44/42 kinase, AP-1, and NF-kappaB pathways.

A highly sensitive, rapid and selective liquid chromatography-tandem mass spectrometry(LC-MS/MS) method for the quantitative determination of retinamido-ester in rat plasma was developed and validated. A simplified protein precipitation with acetonitrile was employed for the sample preparation.The separation was carried out on an Agilent TC C18 column ( 150 mm×4. 6 mm ID, 5 μm particle size)with the mobile phase consisted of methanol-water-formic acid (93 : 7 : 0.1). Simvastatin was used as internal standard. The detection was performed on a trap-quadrupele tandem mass spectrometer by selected reaction monitoring (SRM) scan mode via atmospheric pressure chemical ionization (APCI). The range of and inter-day precision values were between 95.97% and 104. 43%, and RSD was between 4. 63% and 10. 69%, respectively. This method was applied to determine the pharmacokinetic parameters. The main pharmacokinetic parameters of retinamido-ester after oral administration via gastric gavage of 2. 5, 5, 10mg·kg-1 were as follows,T1/2;(11.28±7.23),(8.90±3.82),(8.01±5.56)h; AUC0-∞:(103.41±61.46),(190.23±74.99),(421.66±299.20)ng·h·mL-1;MRT:(6.31±0.75),(5.98±0.71), (6.18±0.97) h; CL/F: (30. 10 ± 13.67), (29.58±10.59), (31.18 ±17.51)L·h-1·kg-1;Vd/F:(414.94±159.82),(356.16±139.85),(369.28±322.73)L·kg-1,respectively.

BACKGROUNDPeroxisome proliferator-activated receptor (PPAR) alpha is one of the subtypes of PPARs. It regulates metabolism of lipid and lipoprotein, as well as glucose homeostasis. In addition, PPARalpha influences cellular proliferation, inflammation, differentiation and apoptosis, which plays a vital role in cardiovascular diseases. The purpose of this study was to investigate the role and mechanisms of PPARa activation in relation to acute myocardial damage induced by isoproterenol in rats.
METHODSThirty male Wister rats were randomly divided into control group, isoproterenol (Iso) injured group and fenofibrate (FF) treatment group. Acute myocardial damage caused by isoproterenol intraperitoneal injection induced ischemia was established. We determined the levels of creatine kinase (CK) and lactic dehydrogenase (LDH) in serum as well as the concentrations of free fatty acids (FFA) in serum and myocardium. The mRNA expressions of PPARa, muscular type carnitine palmitransferase (M-CPT-I) and medium chain lipid acetyl coenzyme A dehydrogenase (MCAD) were analyzed by reverse transcription-polymerase chain reaction (RT-PCR).
RESULTSCompared with the control group, the levels of serum CK and LDH were significantly increased after FF and Iso treatments. Moreover, the concentrations of FFA in both serum and myocardium were obviously increased in the Iso group and FF group, while the mRNA expressions of PPARalpha, M-CPT-I and MCAD declined, respectively (P < 0.01). When compared with the Iso group, significant decreases in serum CK and LDH were observed in the FF group. The concentrations of FFA both in serum and myocardial tissue were markedly decreased in the FF group, while the expressions of PPARalpha, M-CPT-I and MCAD mRNA were increased (vs. Iso, P < or = 0.01).
CONCLUSIONSThe utilization of FFA was reduced in isoproterenol induced acute myocardial damage. PPARalpha activation by its activator fenofibrate may play a key role in energy metabolism in acute myocardial damage induced by isoproterenol in rats.
